How to Pick a Pin-and-Tumbler Lock: Tools and Techniques Explained

13

You don’t need a locksmith’s kit to open a standard door. Most of us carry the essentials in our pockets every day. A paperclip works as a pick. A flathead screwdriver doubles as a tension wrench. The tools you need to pick a lock depend entirely on the mechanism inside. But generally, you are looking for two things. Long, thin metal pieces with curved ends. And something to apply rotational pressure.

Most residential deadbolts use a pin-and-tumbler system. It is the most common type of cylinder lock found in homes. And it is relatively easy to manipulate. You start by inserting your tension wrench into the bottom of the keyhole. Turn it slightly, as if you are about to insert a key. This applies shear line pressure.

Next, you lift the pins. Use a pick to reach into the hole. Find the first pin. Lift it until you feel or hear a click. That click means the pin has set. Move to the next one. Do it one by one. Keep applying that pressure with the wrench. If you do it right, the plug turns.

The concept of lock-picking is simple, but it takes some practice to get good at it.

Not all locks are created equal. Wafer-tumbler locks are even easier to pick. They work on the same principle. But instead of round pins, they use flat, wafer-shaped tumblers. You will notice a wider keyhole. This makes it easier to fit your tension wrench into the slot. Tubular locks are a different story. They are much harder to pick. The pins are arranged in a circle inside the lock. Your standard straight picks won’t work well there.

If individual picking feels too slow or you are struggling with the pins, try raking. It is less precise. You insert a wider-tipped pick all the way to the back of the lock. Then you yank it out quickly. Do this while turning the tension wrench. The vibration shakes some pins into place. Once you hear those clicks, you can go back and pick the remaining pins individually.

Some people use electric pick guns. The tip vibrates rapidly. It mimics the raking motion. You turn the gun while it buzzes. It is essentially mechanical raking. But even with a gun, you still need to manage the tension. The concept remains the same. Apply pressure. Feel for the set pins. Turn the plug.

It takes time to develop the feel. You might break a few paperclips. You might struggle with the first few deadbolts. That is normal. The pins don’t always click loudly. You have to learn to trust your fingers more than your ears. Start with an old lock you don’t care about. Practice until the sequence becomes muscle memory. Then you can move on to the real thing.
